46 Glaims. '(Cl. Mil-287) The present invention relates to shoe machinery, and more particularly to machines adapted to perform during a single cycle of actuation the two operations of perforating or cutting shoe upper blanks such as Vamps, tips, quarters, foxings, straps, or the like to form ornamental cutouts and/or designs therein and of applying ink or other marking substance to said blanks in the form of lines which function as guides for subsequent operations such, for example, as the application of ornamental stitching to the blanks or the assembly therewith in proper position of other upper parts.

So far as I am aware, the production of such" guide lines and ornamental cutouts or perforations on shoe upper blanks is accomplished in either of two general manners. In the one case the formation of a perforated or cutout design is an operation entirely separate from the formation of guide lines. An upper blank is placed in a perforating or cutting machine or on a block and is punched or cut in accordance with the design formed by the cutting elements of a die, and thereafter, upon removal from the machine or block, the blank is provided with guide lines either manually with the aid of a stencil or by a marking machine, sometimes referred to as a stitch marker. The order of the above procedure may be reversed. In the other case the blank is placed in a combined cutting and marking machine, and during a single cycle of actuation thereof the blank is both perforated or cut and provided with guide lines.

The cutting operation may include the punching of small perforations arranged in a pattern or design, or it may be the cutting out of one or more fairly large openings of ornamental or utilitarian nature, or it may be in the nature of pinking or forming ornamental edges on the work, as

' in the case of a wing tip or foxing.

matter today the very important item of expense.

The considerable advance in the art which such machines constitute is recognized by all shoe manufacturers, but to date these machines have been as a whole of a special type and are so expensive as to be beyond the reach or interest of many shoe manufacturers and in any event area sizable item for even the larger manufacturers.-

With these facts in view, it is the principal object of the present invention to provide inexpensive mechanism by which the two operations of While perforating or cutting and guide line formation may be performed during a single cycle of actuation of a single machine.

It is a further object of the present invention to provide mechanism which can be installed in numerous, well known, and long existing machines which have been used heretofore merely for perforating or cutting, thereby transforming them into combined cutting and marking machines.

To the accomplishment of these objects and of such others as may hereinafter appear, the various features of the present invention reside in certain constructions, combinations, and arrangements of parts, hereinafter fully set forth and then pointed out in the appended claims, the advantages of which will be readily appreciated by shoe manufacturers and others skilled in the art.

The various features of the present invention will be readily understood from inspection of the accompanying drawings, illustrating the best embodiment of the invention at present known 'to the inventor, in which:

For purposes of disclosure only, the various features of the present invention are illustrated as beingembodied in the perforating or cutting machine disclosed in the patent to Joseph C. Knight, No. 1,584,230, May 11, 1926. As shown herein (Fig. 1) the Knight machine is provided the above-described structure is to beconsidered as merely representative of numerous long-existing and well known cutting machines, for I am fully aware that embodiments of the present invention may be used in many such machines and are not confined to use in the particular machine herein selected for purposes of disclosure.

For example, the use of the anvil 39 is not essential, as the invention is readily adaptable to flat bed machines, using flat bed dies, as well as to other types of presses, which have long been used for the general purpose in this art.

The anvil 30 in the herein illustrative embodiment is not the same, however, as that disclosed in the above Knight patent, but is preferably of the type disclosed in my Patent No. 2,125,803, More particularly, the anvil 33 cameos shares in common with other anvils the function of supporting on its upper surface and beneath the plunger 26 a die structure of the flat bed type, but is provided with a die structure guideway comprising parallel vertical plates 32 and 33 Figs. 2 -6 and 19-21, as the case may be) portions of which rest upon, and other portions of which extend forwardly from, the upper surface of the anvil. Each plate is provided with depending and inverted T-blocks 33 and 35 (Figs. 2 and 3) which are received in inverted T-ways 36 and 3?, respectively, formed transversely of the anvil in its upper portion. The T-blocks 34 and 35 are slidable across the anvil in the ways 36 and 3'1,

and to efiect this operation in the desired manner the plates 32 and 33 are each provided with a depending hub 38, which hubs receive the right and left hand threaded portions, respectively, of a rod 39 journaled in a bracket 40 attached to the front of the anvil. By turning the rod 39 one way or the other, the plates 32 and 33 are simultaneously moved toward or away from each other in parallelism equal distances from the medial line of the bed 25 and the anvil 30 in order to accommodate and embrace the opposite sides of die structure bases of varying widths.

Spaced above the anvil itself the plates 32 and 33 are provided with upper inturned flanges 4| and 32, respectively (Figs. 2, 3, 5, 6, and 21, as the case may be) the bottom face portions of which are adapted to engage the lateral top face margins of a die structure base or block 43 (Figs. 2 and 3) to keep the die structure from bouncing after reciprocation of the plunger 26 to cause the die structure to operate upon the work. Forwardly of the anvil 30 the plates 32 and 33 are higher than are the portions thereof overlying the anvil, and these forward plate portions are provided (Figs. 2, 3, 5, 6, 19, 20, and 21, as the case may be) with upper inturned flanges. and 45, respectively, forming rearward shoulders 46 and 4'! with the flanges 4i and 42, respectively. While the bottom face portions of the flanges 44 and 45 are aligned with and are continuations of the corresponding face portions of the flanges 4| and 42 in keeping with the showing in my said Patent No. 2,125,803, in the illustrated embodiment of the present invention theflanges 44 and 45 are higher than those shown in my said patent, their tops and those of the forward plate portions being in a horizontal plane above the tops of the flanges M and 42, as indicated in Figs. 2, 5, 6, and 21. Also forwardly of the anvil 30 the lower portions of the plates 32 and 33 are provided (Figs. 2, 4, 5, 6, and 19, as the case may be) with inturned flanges 33 and 69, respectively, the top face portions of which are at the level of the top surface of the anvil 33 (Fig. 4) and are. adapted to underlie the lateral bottom face margins of the die .structure base, cooperating with the bottom face portions of the flanges 43 and 45 and with the intermediate portions of the plates 32 and 33 to form ways and 5| (Figs. 2-6 and 19-21, as the case may be) for supporting and guiding the die structure in its movement from a position where it is forwardly of the anvil 30 and clear of the plunger 26 into and out of a location upon the anvil (Figs. 2 and 3) and beneath the are parallel and horizontal. As best shown in Figs. and 6, the slots 52 and 53 areformed well above the ways 56 and ii to permit the formation therebetween of narrow grooves 64 and 65, re-

' spectively (Figs. 2, 3, 5, 6, 19, 20, and 21, as the case may be) As best shown in Fig. 6, the groove 55 has a top wall terminating forwardly at the front of the flange 45 and terminating rearwardly in an arcuate wall 56 leading downwardly to the way 5|. The top wall of the groove 54 is formed in the same manner, and taking the. lower wall of the groove 55 as an example, the lower walls of both grooves terminate forwardly short respectively, deeper than the grooves 54 and 56 and communicating at their tops with the tops of the flanges 66 and 65 and at their bottoms with the ways 56 and bi, respectively. The above grooves and slots function to receive parts to be described later, but they are mentioned here for the purpose of completing the description of the physical characteristics of the illustrated guideway.

The type of diestructure forming a feature of the present invention has certain elements to be found in many die structures which function merely to perforate shoe upper blanks, but it differs from them in that marking die elements are incorporated therewith. The particular structure herein illustrated and described is designed to operate on a vamp blank 59 (Fig. 3),

of die structure is adapted for forming a wide variety of perforation designs and guide mark- :ngs and is not confined to use on merely a vamp.

Referring to the drawings (Figs. 7-14) the die structure is provided with the die block or base 43 adapted to rest on the anvil 36, the usual tubes 66 for forming perforations in the work piece, a tube plate 6i, and a tube rest plate 62. The two plates are secured to the base 43 by means of screws 63 (Fig. 9) and are aligned by means of pins 64 (Figs. 8, 9, and 10) as is customary, and the base 43 and the tube rest plate 62 have the usual aligned holes 65 and 66, respectively. (Figs. 8, 11, 12, and 15) through which punchings may pass downwardly from the tubes 66 to a recess 61 formed in the bottom of the base 43. The die structure is also provided with a stripper plate 68 (Figs. 7-15) from which depend four posts 69 (Figs. 7, 9, and 10) received in aligned openings I6 and 16A (Fig. 10) formed in the tube plate 6| and tube rest plate 62, re spectively, and around which springs II are coiled for interposition between the stripper plate 68 and the top of the base 43 The bottom of the base 43 is provided with recesses 12 (Figs. 8 and 10) wider than but aligned with the openlugs 16 and 16A so as to form shoulders I3. As shown in Fig. 10, there is a passage 14 connecting each pair of openings IO-16A and recess 12 for slidably receiving the associated post 69, a screw 15 being threaded up into each post so that the screw head abuts the associated shoulder 13. The stripper plate 68 is provided with the usual opening 16 (Figs. 9 and 11-15) forming a clear- -ance area for the tubes 66, and in the illustrated embodiment of the present invention the normal level of the stripper plate is such that its top surface is in the plane of the tops or perforating edges of the tubes 66. To complete the stripper plate structure, it is provided with a gauge plate ll (Figs. 1, 3, 7, and 9-15) having a wall configuration for registry with the throat of the vamp blank 59, and there are also provided the usual clips 18 (Fig. 3) for maintaining the work piece in position on the stripper plate in registry with the gauge. By reason of the above construction, the heads of the screws '15 limit the upward movement of the stripper plate to the level stated, while the sliding fit of the posts 69 in the passages it permits movement of the stripper plate 68 toward the die structure base under the influence of pressure, as provided bythe plunger 26. As a consequence, and as is well understood, when a work piece is mounted on the stripper plate 68 and the die structure is on the anvil 36, descent of the plunger presses the stripper plate 68 and the work piece downward, causing the stationary tubes 66 to pierce and perforate the work piece, after which, upon the rise of the plunger, the springs ii force the stripper plate up to its normal position and in so doing effect the stripping of the work piece from the tubes.

In order to provide for marking guide lines on awork piece during the perforating operation, the present invention contemplates the association with the above-described structure of a marking die and actuating elements therefor. To this end, and with reference to Figs. 7 and 9-15, the illustrated embodiment of the present invention is provided with a plate 16 having upstanding thereon ridges 86 the tops of which adjacent ridges 86 the plate i9 is provided with openings 82 (Figs. 9, 11, 12, and 15) through which the tubes 66 freely extend, and it will be seen that for disclosure purposes the ridges 86 are shown (Fig. 9) as conforming to the design formed by the tubes 69. The plate 19 is somewhat smaller than the clearance opening 16 in the stripper plate 68, as shown in Fig. 9, and is positioned over the tube plate (ii for vertical movement away from and toward the base, as will be described. For guiding the plate 19 in this vertical movement three posts 83 (Figs. 7, 8, and 9) depend from the plate and are slidable in passages 84 formed by aligned openings extending through the tube plate 6!, the rest plate 62, and the die blockor base 43.

In one aspect of the present invention, the marking die formed by the plate 19 and its ridges 86 may be supported merely by engagement flatwise with the tube plate 61. It is preferred, however, that the marking die be resiliently supported, and to this end the plate I9 is provided with four depending posts 65 (Figs. 9, 11, 12, and 15) which are shorter than the posts 69 and are received in passages 86 (Figs. 8, 9, 11, and 12) formed by aligned openings extending through the tube plate 6|, the rest plate 62,

and the base 43. Also received in each passage 86 is a spring 81 loosely coiled about its associated i post 85. The top of each spring 81 engages the under face of the plate 19 and the bottom of each spring 81 rests on a button 68 (Figs. 11 and 12), and forming a support for each button is one end of an associated lever 89. As best shown in Fig. 8, the levers 89 are four in number, are parallel with the lateral edges of the base 93, are positioned in aligned pairs, and are located in slots 90 formed in the base 89. Intersecting the slots 90 substantially at their mid points are vertical blocks 91, respectively (Figs. 7, 8, 11, and 12), each provided with a slot 92 in which its associated lever 89 lies and is pivotally mounted therein by means of a horizontal pin 93. With reference to Fig. 11, it will be seen that the portion of each lever 09 extending from its pivot inwardly of the base 03 has a bottom face lying in the plane of the bottom of the base, while the bottom face of the portion of each lever 89 extending from its pivot outwardly slants upwardly. With this construction the length of the springs 81 is such that as each rests on its button 88 with the levers.89 in their Fig. 11 position, the marker plate 'I9 is spring-supported at such a level that its marking edges 8! are retracted,

i. e., are below the plane of the tops or periorating edges of the tubes 60. In the illustrated embodiment of the present invention this position of the marking edges 8| is their normal position, one in which the edges III are substantially in the plane of the lower face of the stripper plate 68. By reason of the above-described structure it will be appreciated that the plate I9 assumes by gravity the position of normal retraction of the marking edges 81.

The present invention contemplates that in the use of the above-described structure the marking die shall be elevated from its Fig. 11 or normal position in two different manners and for two difi'erent purposes, one for applying marking substance, preferably a suitable ink, to the marking edges 8|, since such application is not practicable while the marking edges are below the tops of the tubes 60, and the other for the purpose of moving the inked marking edges BI into engagement with a work piece supported by the stripper plate 68. To the last of these ends the structure described in the paragraphs immediately above is utilized, and for this purpose the die block or base 93 is provided with four passages comprising a front pair 94 and a rear pair 95, as indicated in Figs. 11 and 12, each passage being aligned with the free end of a lever 89, as best shown in Figs. 11 and 12, and slidable in the passages 99 and 95, respectively, are front pins 96 and rear pins 97 (Figs. 9-14) having rounded heads underlying the stripper plate 68. Collars 98 mounted on the base 43 and encircling the pins 91 prevent the latter from falling from the die structure, and since the presence of the gauge plate 11 on the rear portion of the stripper .plate necessarily causes said portion to flex downwardly (Fig. 12) under the influence of the plunger 26 before the remainder of the stripper plate moves, as is well known, the rear pins 91 are shorter than the front pins 96.

With this arrangement, it will be seen that when the stripper plate and supported work piece descend, as under the influence of the plunger 26, the stripper plate presses against the pins 96 and 91, thereby swinging the outer portions of the levers 89 downward and so causing the inner portions of the levers to swing upward simultaneously. This necessarily causes the buttons 80 to rise, thereby forcing-the springs 01 upwardly. to

elevate the marker plate I9 and the marking edges BI and cause the latter to engage the work piece to mark it.

In order to elevate the marking edges 8| above the plane of the tops or perforating edges of the tubes 60 so that ink or other marking substance may be deposited on the marking edges to the exclusion of the tubes, a different plate '19 elevating mechanism than that described above is contemplated. To this end the tube plate 6i, the rest plate 62, and the base 03 are provided with aligned openings forming passages 99 (Figs. 13 and 14) so located as to underlie the marker plate I9 adjacent its corners, respectively. Slidably received'in each passage 99 is a pin I00 (Figs. 7, 8, 9, 13, and 14). having an annular boss I01 adjacent its upper end which forms with the body of the pin an upper shoulder I02 (Fig. 13) and a lower shoulder I03 (Fig. 14), the latter being normally supported by the tube rest plate 62 as the pin passages 99 (Figs. 13 and 14) each have an enlarged portion I09 in the tube plate M for this purpose. The pin portions above the bosses IOI project into openings I05 (Figs. 9, 13, and 14) formed in the marker plate I9 in alignment with the pin passages 99, and the lower ends of the pins I00 at the opposite sides of the marker plate are, in pairs, threaded into horizontal bars I06 and I01, respectively, (Figs. 7, 8, l3, and 14) located in grooves I08 and I09, respectively, formed on the bottom of the base 03 and intersecting the pin passages 99. As shown in Figs. 7,.13, and 14, the bottoms of the opposite end portions of the bars I06 and I01 are upwardly curved, and the length of the pins I00 is such that when the pin shoulders I03 engage the tube rest plate 62, the bottoms of the bars I06 and I0'I are in the plane of the bottom of the base 43.

When the bars I06 and IM are thus positioned (Fig. 13), it will be appreciated that the pin shoulders I02 do not abut the under face of the marker plate I9 at all and form no support for it, the plate support remaining, as described above,

the tops of the springs 81, as shown in Fig. 11,,

upon which the plate gravitationally rests. However, as the space between the top of the grooves I08 and I09 and the tops of the bars I06 and I01, respectively, is greater than the normal spacing between the adjacent faces of the marker plate I9 and the tube plate 6| as the marker plate rests on the springs 81, it will be appreciated that when the bars I 06 and I0! are elevated, as will be described, the pins I00 are elevated so that the pin shoulders I02 first abut the under face of the inarker plate I9 (Fig. 14) and then elevate it, causing the plate 19 to be supported by the shoulders I02 and no longer by the springs 81.

It will also be appreciated from comparison of Figs. 13 and 14 that when the bars I06 and IM are elevated so as to engage the tops of the grooves I08 and I09, respectively, the marking edges M are above the tops of the tubes 60, for the spacing differential between the tops of the bars and grooves on theone hand and the adjacent. faces of the tube plate BI and the springsupported marker plate I9 on the other is made great enough to achieve this end.

In order to elevate the bars I06 and I0! and so elevate the marker plate I9 as described above, it is contemplated in the illustrated embodiment of the present invention that this be achieved by cam action and while the die structure is located in the ways 50 and 5| of the guideway portion in advance of the anvil 30. To this end horizontal plates H0 and III (Figs. 2, 3, 4, and 6,

as the case may be) are secured to the lower faces of the flanges 48 and 49, respectively, ahead of the hubs 38, and at their free or inner edges the plates are provided, respectively, with upstanding cams H2 and 3. As shown best in Fig. 14, the opposite ends of the cams are rounded downwardly, and since it is contemplated that the cams perform their elevating function while the die structure is located in the ways 50 and St,

the cams are located far enough inwardly of the V flanges 48 and 49 as to be in the vertical planes of the bar grooves I68 and I 09, respectively, in the bottom of the base 43. The height of the cams H2 and H3 is such (Fig. 14) that when engaged with the bottoms of the bars Hit and ill, the bar tops engage the tops of the associated grooves Hi8 and I09, and with this construction, plus the fact that the opposite ends of the bars I06 and illl are upwardly curved, it will be seen that both when the die structure is initially received by the ways 56 and i and also when the die structure is pulled outwardly from the anvil 3t and along the ways 5t and 5E by the usual handle (not shown), the bars "it and ml engage the cams and ride smoothly up and along them to cause elevation of the marker plate ill so that the marking edges dl are above the level of the tops or perforating edges of the tubes dd.

In order to deposit marking substance on the marking edges ll when elevated as just described, it is contemplated in the illustrated embodiment of the present invention that a roll be provided to deposit the marking substance on the edges by rolling contact therewith. While this may be achieved by moving the die structure while engaged with a roll having a stationary mounting, it is preferred that the opposite procedure be followed, that is, that the roll be.

moved bodily in contact with the marking edges when they are stationary. To this end the illus trated embodiment of the present invention is provided with a rigid frame comprising spaced end plates i Mi (Figs. 2-6 and 21) which receive and are secured to the opposite reduced end portions of an upper rod lldand two lower rods lit located in a horizontal plane, and journaled in the plates i it are the opposite ends of a shaft lll somewhat longer than the width of the top of the anvil fill (Figs. 3 and 4) and having a preferably sponge rubber cover lid of substantial thickness forming a marking substance applying roll lit. Also journaled in the plates ill are the opposite ends of a somewhat narrower shaft ill, in length commensurate with the shaft M! and having a rubber coverl2l forming a roll l22 the surface .of which is preferably smooth. By reference to Figs. 2, 5, 6, and 21, it will be seen that the roll H2 exerts a slight pressure on the roll lit! thereby being rotatable by rotation of the roll lid and functioning not only to spread along the roll l it marking substance applied thereto in any suitable manner but also to squeeze the roll ill? to bring to its surface marking substance caught in its voids.

It being contemplated that the roll lit shall move in rolling contact over the elevated marking edges ti to deposit marking substance upon them, it will be apparent that for this operation the roll lit must be located at such a level that its lowermost element is in substantially the same plane as that of the marking edges tl when elevated, and of course not above that plane. It will also be apparent that since the die'structure is located forwardly of the anvil ill in the ways Eli and Jil when elevation of the marker plate ill occurs, the roll ll 9 and associated roll l2? and frame must be movable alon the track formed by the plates 32. and 33 and the flanges M and E5 in order that the roll H9 may engage the elevated marking edges tl. To achieve these ends, the horizontal rods lit are slidably received by the apertured upper arms of two identical yoke plates I23 (Figs. 2-6 and 19-21) the lower portion of each of which comprises a centrally disposed and apertured downward extension :24. These extensions are adapted to be held in engagement with the outer faces of the plates 32 and 33, respectively, and the apertures of the extensions are so spaced downwardly from the roll lll as it is supported from the yoke plates in that when the extensions engage the plates 32 and 33 in proper position, the lowermost element of the roll M9 is in substantially the same plane as that of the elevated level of the marking edges ll as stated above. In order to secure the extensions i ll in this position, each receives a bolt lzi'q having a flange llt engaged with the outer face of the extension and also having a shank which extends through the associated slots 52 or 53 and is threaded into a slide block it'll located in the slot. As shown best in Fig.4, each bolt l 25 extends outwardly from its flange in and is provided on its free end with a handle l'lt.

With'reference to Figs. 2, 5, 6, and 21, it will be seen that each of the slide blocks lfl has ends that are rounded in conformity with the rounding of the ends of the slots 52 and 53 and also has parallel top and bottom surfaces in flatwise contact with the top and bottom walls of said slots, respectively. As indicated in Figs. 19 and 20, however, while the outer sides of the slide blocks ltl engage the inner faces of the associated yoke plate extensions ill, the slide blocks do not extend to the inner faces of the flanges ll and 35 but terminate short thereof, and the intervening space is filled in each case by a squared boss l2t extending from the outer face of a vertical plate ltd, which outer face engages the adjacent face of the associated flange lltl or l5. By reason of the above constructions it will be seen not only that the roll i it is supported so that its lowermost element may be in substantially the same plane as that of the marking edges ll when elevated but alsov that the bolt flanges ltd and the yoke plate extensions lfid on the one hand and. the plates ltl with their bosses ltd on the other hand hold the slide blocks lf'l in position laterally with respect to the slots 52 and 53. As a consequence, the slide blocks can move only lengthwise of the slots 52 and El, and when the handles lft, for example, are pulled forward or pushed backward, the rolls lid and l 22, their mounting frame, the yoke plates ill, the slide blocks ill, the plates ill, and the bolts ltd move forward or backward as a unit.

It will be appreciated, however, that if the only ultimate support for the roll i it is the bolts lid, there will be a tendency during operation for the rolls ll 9 and l 22, their frame, and the yoke plates lft to swing forward and downward or rearward and downward about the pivot or axis provided by the bolts lft. To prevent this undesirable occurrence, that is, to maintain the roll lld always at the proper level for deposite ing marking substance upon the marking edges ti when elevated, the illustrated embodiment of the present invention is provided with steadying means for the roll ill! in the'form of cylinders ill (Figs. 2-6 and 19-21) mounted on bolts ltd carried by the yoke plates ltd above the guideway plates 32 and 33. With particular reference to Figs. 6 and 21 it will be seen that each yoke plate its is provided with two cylinders ldl located one to each side of the associated block ill and bolt are and that the cylinders EM engage the tops of the associated guideway plates for rolling contact therewith as on a track while the slide blocks in move in the slots 52 and 53. By reason of the above construction, it will thus be seen that the yoke plates B23, and therefore the rolls H9 and I22 and their frame, are maintained at; a constant level, i. e., their tipping forwardly or rearwardly about the axis provided by the bolts 5 is prevented by the location of the cylinders Hi, and

that the rolls H9 and i2! and their frame are,

movable at the constant level thus provided forward and backward over the guideway plates 32 and 33, as will be described.

Eonsideration of the entire structure thus far set forth will show that an operative organization. has been provided by which thefmarking edges 8i may receive marking substance for transfer to a work piece. More particularly, it will be seen that the above-described structure is operatively complete and may be placed in a perforating machineas a unit, thereby making the machine a combined perforating and marking machine. A die structure may be inserted by its block or base fit into the forward part of the ways 5d and 5!, and as the cams H2 and i I 3 would effoot elevation of the marking edges Bi, the handies 62% could be manually pulled forward. thereby bringing the roll H9 into rolling contact with the edges hi to deposit marking substance upon them. The handles 928 could then be pushed rearward with the roll H9 in rolling contact with the edges 8i, whereupon the die structure could be pushed rearward far enough to cause the bars Hi5 and is? to ride on their associated cams, thereby causing the marker plate 89 to be retracted. Upon then placing a work piece properly on the stripper plate 58, the die structure could be pushed in the usual manner onto the anvil 39 for descent of the plunger 25. But while this mode of operation is entirely possible, it has the double disadvantage that it is slow, for the roll M9 and associated structure must be manually moved forward and then manually moved backward before each sliding of the die structure onto the anvil, and that the forward and backward movements of the roll H9 and associated structure necessitate depositing marking substance on the marking edges 8i twice for each time the die structure is prepared for work reception and positioning on the anvil. As an alternative, the roll .i is need not be moved rear- I ward after first depositing marking substance on the markingedges 89, but may be left forwardly on the guideway while the die structure is pushed rearwardly .and provided with a work piece as stated above. Then, upon a completion of operatlon upon that work piece and sufficient withdrawal of the die structure from the anvil 36 so that the work piece may be removed and the marker plate 79 thereafter elevated by further movement of the die structure, the roll H9 and its carriage may be manually moved rearwardlv to deposit marking substance on the elevated edges 8!, whereupon the die structure is moved rearwardiy for work piece reception and anv l mounting as first stated. It is recognized that this procedure eliminates a double depositing of marking substance on the marking edges M for each-time the die structure is prepared for work piece reception and positioning on the anvil, but there still remains the necessity of moving the roll HQ forward manually and of moving it rearward manually as operations entirely separate from the operations of moving the die structure itself.

In order to avoid anyof the manual movings of the roll H9 as stated above and in order to prevent any double depositing of marking substance on the marking edges 8!, it i contemplated that in the illustrated embodiment of the present invention power means be provided for causing movement of the roll i IS with respect to the guideway to deposit marking substance on the marking. edges BI and that means be provided so that this depositing of marking substance need occur only once for each time the die structure is placed on the anvil 30. While the power means referred to may take any form suitable for the purpose and be controlled in any suitable manner, it is preferred that the power means comprise springs the action of which is controlled by the die structure itself during'its movement in the ways 50 and 5!.

With reference to this power means, each of the guideway hubs 38 (Figs. 1-6) is provided at its upper rear portion with a bolt I33 the shank of which extends beyond the outer face of the hub and forms an axle fora spool comprising an inner disk iiii, a cy1inder I35 (Fig. 5) secured thereto, and an outer disk 36, these spool components being held together on the bolt E33 by means of a nut itl. With particular reference to Fig. 5,-the cylinder 835 is provided with a slot wt, and adjacent thereto with arivet i39 which functions to secure tothe inner face of the cylinder one end of a strap MB and also one end of a coil spring ml the other end of which is inserted in a slot M2 formed in the bolt i33. the rivet i39 the strap Mil extends along the inner surface of the cylinder Hi5 to the slot 838 and then passes therethrough to form several convolutions on the outer surface of the cylinder, and the free end of the strap ifiili extends upwardly and forwardly and is provided with a loop M3 in which'is located a portion of the bolt I25 extending between the bolt flange 126 and the handle are. As the spool, spring, and strap components are identical on each side of the guideway,

it will be seen that the springs Mi when in their normal (Fig. 5) condition, tendto maintain the straps Mt coiled around the cylinders 35, and by this action tend to maintain the bolts I25 and therefore the roll H 9 in a retracted, i. e., rearward, position with respect to the track formed by the guideway. The rearward limit of this retracted position is, of course, the rear curved ends of the slots 52 and 53 which the slide blocks i2! abut, just as the forward curved ends of the slots 52 and 53 limit the extent to which the roll H9 and its carriage may be moved forwardly, it being noted that the forward ends of the slots 52 and 53 are suficientl'y spaced rearwardly from the front face of the plates 32 and 33 so that springs it! by the forward pulling on the handles m8 is also released, thereby causing the straps i 39 and therefore the roll H9 and its carriage to move rearward automatically without further effort on the part of the operative.

The fact has been pointed out above that even n e absence of elements such as the straps MG From and the springs I II the above-described apparatus is operative in either of two ways for preparing a die structure for the combined operations of perforating and marking. It will therefore be appreciated that because of the straps I40 and the springs MI a faster mode of operation is provided in that the presence of these elements eliminates one of the manually effected movements of the roll H9 and its carriage on the guideway. But while this automatic roll retrac- 2-6), and the forward swinging ceases only when' the front faces I50 are swung up into engagement, with the under faces of the guideway flanges. After this engagement point is reached, no furvther swinging of the fingers I44 and I45 can take tion is an improvement over the alternative modes of operation set forth above, there is the possibility of further improvement by providing means for completely eliminating all manual movements of the roll I I9 and its carriage to deposit marking substance as an act or acts separate from moving the die structure itself. To achieve this desirable mode of operation the illustrated embodiment of the present invention is provided with means operatively connectable with the die structure by which the roll IIQ and its carriage are moved forward as the die structure is moving in the ways 50 and ti away from the anvil 3t.

With particular reference to Figs. 4, 19, and 20, I

the bolts I do not terminate at the inner faces of the vertical plates I but instead extend beyond them to support depending left and right hand fingers I A l and I45, respectively, and also nuts I and weak springs I M coiled about the bolts and interposed between the respective nuts and fingers. Each depending finger Md and M35 is provided with an aperture Mt (Figs. 16, 17, and

.18) of greater diameter than the shank of the bolt I25 whichit freely receives, and normally is yieldingly pressed into engagement with its associated plate I30 by its spring It? so as to normally hang vertically from its bolt I25 with the bottom portion of the finger facing the'associated way or 5i, as 'shown best in Fig. 4. The fingers IM and M5 are of complementary construction, and with further reference to Figs. 16, 17, and 18, they inner face of the finger M5 is provided at the right side of its lower portion with an arm M9 extending outwardly therefrom at right angles thereto, and the arm is provided with a rearwardly and upwardly extending front 'face I50 (viewing Figs. 4 and 16), a rear surface having a slabbed off face I5I, and a vertical 7 end or side face I52 of somewhat triangular shape by reason of the position of the surfaces I50 and I5I. As shown best in Figs. 16 and 1'7, the top edge I53 formed by the junction of the converging faces I50 and I5I is curved downwardly and. forwardly, meeting the end face I52 at a point I5A. The finger Hi l has a corresponding construction, the outstanding arm I there of extending from its left or inner face (Fig. 4) and both arms I55 and I49 have such a height that by reason of their being outstanding from their fingers, they extend into the ways 58 and 5i, respectively (Fig. 4) when the fingers are hanging vertically.

In view of this. arrangement it will be seen that while the arms I55 and its are so located, they and their associated finger portions are in the path of travel of the die structure base It when moving from the anvil at in the ways 56 and 5B be seen that when the die structure is pulled forwardly far enough so that the base it engages place, but inasmuch as the fingers are operatively connected through the bolts I25 to the roll H9 and its carriage, it will be seen that as the die structure continues to move forward, its block or base 63 continues to push on the fingers, thereby causing their forward movement bodily, and simultaneously causing the forward movement of the roll I I9 and its carriage. In this manner the die structure itself controls and effects forward movement of the roll I I9, causing it and its carriage to move forward ahead of the die structure as the latter is forwardly moved in the ways 5Il and 5i, and no act separate from that of merely pulling the die itself forward in the ways 50 and iii is necessary to effect this roll and' carriage movement.

Although the forward movement of the roll I I9 and its carriage in the above-described manner continues as long as the finger arms I55 and M9 continue in engagement with the under faces of' the flanges M and t5, respectively, it will be seen that while the die structure base 43 is pushing the fingers IM and M5 forward it is also pushing them upward against the resistance offered to the fingers I55 and M9 by the under faces of the flanges. As a consequence, as soon as the forwardly moving die structure base pushes the fingers so far forwardly that their top edges I53 reach the receded and curved front ends of the lower walls of the grooves 56 and 55 (Figs. 2, 5,

6, 19, 20, and 21), the resistance ofiered by the under faces of said flanges ceases to exist and is no longer a bar to further upward swinging of the fingers I (Ill and M5. As a result of this fact, a further forward movement of the die structure causes the front edge of its base I13 to swing the fingers upward. and since the die base has a constant level, the base rides under the fingers.

Referring now to Fig. 18, it will be seen that the point IN is inwardly spaced from the right hand side of the finger as shown in said figure. Specifically, this spacing in such (Fig. 19) that as the die base I13 rides under the finger, the point Ififl is located at a level between the top and bottom walls of the guideway groove 55, and it will be understood that similar statements may be made in this respect about the finger IM and its guideway groove 5 3.

As soon as the arms I55 and M9, respectively, are thus located with respect to the grooves 56 and 55, it will be seen that the fingers Hit and I 15 are no longer subject to the influence of the die structure. Stated in another way, although the force exerted by the operative in pulling the die structure forward in the ways 50 and 5I overcomes the yielding resistance to movement of the roll H9 and its carriage offered by the springs I II, the very act of pulling the die structure for ward serves to wind up the springs and store them with power because of their operative connection with the moving die structure base It. As a consequence, as soon as the fingers I46 and I 35 are free of the influence 0f the die structure base, the stage is set for the release of this stored power, i. e., the stage is set for the springs MI to pull the straps ltd rearwardly, thereby causing the roll ii 9 and its carriage to be retracted until the slide blocks I21 are at the rear of the slots 52 and 53.

This retraction begins immediately upon the riding of the die base 53 under the fingers M6 and 545 to elevate them, and takes place in the illustrated embodiment of the present invention by the cooperation of several factors. The first factor is that as soon as the fingers are thus elevated, they are subjected to the rearward pull of the springs MI in the absence of any counter pull. The second factor is that since the curvature of the top edges i53 of the finger arms H55 and 859 extends initially inwardly and forwardly of the ends of the lower walls of the grooves 5 and 55 when the fingers are thus elevated, the only portions of the arm faces B50 and l5l which engage the walls of the grooves 54 and 55 are the face portions adjacent the fingers themselves, thereby preventing contact of the faces l5t and i 55 with the full width of the walls of the grooves 5 and 55 and hence eliminating the possibility of the finger armsbeing locked at the forward ends of the lower walls of the grooves. The third factor is that the grooves 58 and 55 are considerably narrower vertically than the bottoms of the finger arms H55 and M9 are wide (Figs. 2, 6 and 19), thereby making it impossible for the fingers in their entirety to be located in the grooves 563 and 55. The fourth factor is that the fingers are very loosely mounted on their bolts H25 both because of the relatively great size of the finger apertures i438 and because the springs Mil are weak, with the result that the apertures M8 permit the fingers to swing fiatwise, i. e., toward the bolts H5 and away from the inner faces of the flanges it and t5, and the springs offer little resistance to this swinging.

Putting theabove four factors together, itwill be seen that as soon as the fingers M5 and 555 are free of the influence of the forwardly moving die structure, the springs Hi I, acting through the straps I40 and the carriage for the roll H9, exert a rearward pull on the fingers i6 3 and i 35, and the result of this pull is not only that the fingers Md and M5 are retracted, becausethe operative connection they provide between the die structure and the roll M9 and its carriage is broken, but also that they immediately seeka path of least resistance while being retracted. Stated in another way, since the finger arms use and I69 cannot in their entirety be located in the grooves 56 and 55, since the curvature of the arm top edges I53 prevents a locking of the finger arms against the lower wall ends of the grooves 54 and 55, and since the size of the fin-= ger apertures M8 permits a swinging of the fingers otherwise than about the bolts H25 merely as an axis of rotation, the rearward pull of the springs Mi causes the finger arms I55 and M9 to ride outwardly from the front of the lower walls of the grooves 54 and 55 while also moving rearwardly, thereby resulting in the fingers M6 and M5 swinging away from the fianges t8 and 65 until the finger M5 assumes the angular position shown in Figs. 19 and 20 and the finger Mt assumes a corresponding position. Once the fingers M5 and M5 are so located, the springs t ll immediately pull-the fingers backward with the arms I55 and M9 in the grooves '54 and 55, re-. spectively, and this causes the simultaneous pulling backward of the roll H9 and its carriage until further retraction is stopped by the abutment of the slide blocks i2? against the rear ends of the slots 52 and 53. As the roll M9 and.

enemas its carriage reach their rearmost position, the engagement of the arcuate wall portions 56 (Figs. 2, 5, 6, and 21) with the finger arms E55 and M9 causes the fingers to swing downward until the arms I55 and I49 enter the ways 50 and 5|, respectively, at which time the pressure of the springs M1 against the fingers I44 and 5 causes them to assume their normal or hanging position.

The preceding paragraphs have been devoted to describing the mechanism by which the roll 8 i5 and its carriage are moved forward and-backward over the guideway, and it has been pointed out that the finger arms B55 and M9 and associated finger portions are located in the path of travel of the die block or base'43 at a time when the die structure is about to be pulled forward from the anvil 50 so as to push forwardly on the fingers M4 and M5. But it will be seen that after the arcuate wall portions 56 have caused the finger arms i555 and 9 to enter the ways 55 and 5! upon retraction of the roll H9 and its carriage, these fingers are also in the path of rearward travel of the die base 43 back onto the anvil. This, however, is of no moment. With reference to Figs. 3 and 21 it will be seen that the upright arcuate slots 51 and 58 are deep enough and are so positioned that as the rear edge of the base #33 engages the fingers I44 and M5, the base pushes them up so that the arms l55 and 555 are in the slots 51! and 58 and the base rides under and supports the fingers, and as soon as the front edge of the die base passes the fingers, they swing downward by gravity to their normal position in readiness for the next withdrawal of the die structure from the anvil.

The die structure shown in elevation in Fig. 7

and also shown sectionally in Figs. 10-14 is characterized in one respect by the presence of the levers t9 and pins 55 and 9? which are actuated to efiect movement of the marker plate 79 upward into engagement with the work piece as the stripper plate 55 descends. The alternative die structure shown in Fig. 15 is identical with that shown in the above-mentioned figures, except the absence of the structural elements noted just above, the marker plate 19 in Fig. 15 is not movable upward into engagement with the work piece as the stripper plate 88 descends. It is,

however, movable upwardly by the cams H2 and H3 since it is contemplated that the Fig. 15 construction in common with the die structure shown in the other figures be provided with the pins 590, bars I08 and I01, and associated passages.

In view of the above description of both structural and operative features of the illustrated embodiment of the present invention, it is believed that little need be added by way of summary of the operation of the embodiment as a whole.- There are, however, certain points to which attention is cal-led. Assuming that the roll H9 has been properly provided with ink or other suitable marking substance and that the anvil has been properly positioned on the machine bed 25 and beneath the plunger 25, the first step is that of insuring that the spacing between the plates 32 and with their assoward of them initially is the necessity of placing the finger arms I55 and I49 in the respective grooves 54 and 55 so that-the arms will not strike the rear of the die base 43 and be stopped increase the spacing, and the particular work piece and the particular die structure herein disclosed have been illustrated in Figs. 2 and 3 as being quite small for the purpose of bringing out the. spacing variability possible for the ways 50 and 5|. As commercial anvils may be ten or more inches in width, it will-be apparent that the guideway construction herein disclosed may be used with die structures and work piece arrangements having far greater width and size than those illustrated. By reason of the yoke plate extensions I24 and the slide blocks I21 being held between the bolt flanges I26 and the plates I30 with their squared bosses I29, it will be seen that each of these arrangements neces-' sarily moves with its associated flanged plate 32 or 33 during a turning of the rod 39, with the result that while the spacing betweenthe ways 50 and 5I is being varied, the-yoke plates are simultaneously moving apart or toward each other.- Since the yoke plates. I23 are located between the frame plates II4, and since the width of the areaoccupied by the perforating and marking die elements is less than the distance between the yoke plates, as indicated best in Fig. 3, it will be seen that no matter how far apart the yoke plates I23 may be spaced, a suflicient portion of the roll I I9 is always above the marking die so that its edges 8| may receive marking of marking substance to the marking edges 8|.

This may be accomplished in several manners. If desired, the die structure may be left in the forward portion of the guideway, with the result that the marker plate 19 remains elevated with its edges 8| above the tops of the tubes 60, for it will be appreciated that marker plate elevation thereby. The preferred procedure to use comprises sliding the die structure rearwardly as soon as it ism the ways 50 and 5I until it rests on the anvil 30, i. e., until the depending finger arms I55 and I49 haveswung back down into the ways'50 and 5I from the grooves 51 and 58, respectively, into which they are pushed as the die structure is pushed rearwardly. Y Imme- 'diately thereafter the die structure is pulled forwardly, causing .the base 43 to engage and push on the fingers I44 and I45 and so effect a for,- ward movement of the roll H9 and its carriage ahead of the forwardly moving die structure since the fingers I44 and I45 form an operative connection between the die structure and the roll II9 for this purpose, as has been stated above. As the die structure approaches the forward end of the guideway the bars I06 and I01 will ride up onto the cams H2 and H3 to 55, thereby effecting a breaking of the operative connection which the fingers form between the die structure and the roll II9. As soon as this connection is broken, the springs I4I cause the roll II9 to be retracted, and as the marker plate has been previously elevated, the roll II9 will engage the marking edges 8| while being retracted and will deposit marking substance upon them. This manner of preparing the, marking edges for use is the preferable one since i it causes the roll II9 todeposit marking substance on the edges BI only once and because occurs during the reception of the die structure by the guideway because of the action of the cams H2 and .II3 on the bars I06 and I01, respectively. With the die structure in this forward position, the-operative may grasp the handles I20 and pull them forward so that the roll I I9 engages the marking edges by rolling contact and deposits marking substance upon them, and

thereafter the operative may either release the handles I28, causing immediate retraction of the roll H9 and a second depositing of marking substance on the. marking edges, or he may hold the roll forward while pushing the die structure it is simple, requiring merely the pushing. of the die structure onto theanvil and then immedi- 'ately the pulling of it back onto the forward portion of the guideway. With the marking edges 9| thus provided with marking substance, the die structure is next pushed rearwardly in the guideway sufficiently to cause the bans I06 and I01 to ride off the cams H2 and H3 so that the marker plate 19 assumes by gravity its norsufiiciently rearward to cause the bars I06 and I01 to ride ofi the cams, after which the roll H9 is allowed to be retracted. No marking substance will be deposited upon the stripper plate 68 or upon the gauge", for reference to Fig. 14

will show that the plane of the marking edges I vcondition 'of pulling the roll H9 and its carriage forward when the die structure is located formal. or retracted position with respect to the tubes 60. This being done, a work piece is mounted on the stripper plate .66 and the die structure is pushed re'arwardly onto the anvil in position for actuation of the plunger 26. Reference to Figs. 3, 19, and .20 will show that although the stripper plate is substantially at the level of the bolts I 25 as the die structure is slidably received by the guideway, the stripper plate does not engage the fingers I44 and I45 or the bolts I25 and nuts I46 since the width of the stripper plate is -less"than the spacing.

between these bolts and nuts. a

It has been pointed out above that when the plunger is actuated, i. e., descends, it presses the work piece and the stripper plate downward, causing the tubes 60 to pierce and perforate the work piece, and it has also been pointed out that the marking edges 8| are brought into engage ment with the descending work piece to mark it. In viewof the fact that the work piece normally rests with its under face in engagement with the top edges of the tubes 60, so that said under face is in substantially the plane of the top edges of the tubes and above that of the marking edges 8| when the marker plate, I9 is retracted, and since the marking edges rise into engagement with a work piece that is descending, it will be seen that the engagementplane of the work piece and the marking edges is somewhat lower than that of the top edges of the tubes and somewhat higher than that of the normal retracted level of the marking edges. As a consequence, the effect of become partially pierced by the tubes 60 by the time marking engagement with the marking edges occurs. As a consequence of this piercing action on the work piece prior to its being marked, it will be seen that the present invention does not contemplate dependence, for the maintenance of the work piece in proper position over the" stripper plate opening 16 for marking, merely upon the customary squeezing action resulting from a work piece being between a resiliently mounted stripper plate and a plunger. Supplementing this squeezing, which exists only at and outside of the boundaries of the openin 16 so far as the stripper plate is concerned, is the impalement by the stationary tubes 60 of the portion of the work piecev overlying the opening I6,

and since the tube openings 82 in'the marker plate 19 are located between the marking edge ridges 80, as shown in Figs. 9,11, 12, and 15, the

portion of the work piece overlying the opening I6, in being impalingly pressed onto the tubes 60 by the plunger 26, is held by the tubes from any creeping that might otherwise exist with respect to the marking edges 8|, for it is to be particularly notedthat this holding from creeping always occurs within the boundaries of the opening 16 and in the illustrated embodiment of the present invention adjacently along the very portions of the work piece which are to be marked. There is therefore no danger of the marked lines being blurred or thick, a result which creeping engenders.

The above approach of the marking edges to the plane of the top edges of the tubes 68 takes place shortly after the work piece and stripper plate begin to descend, aswill be appreciated. If the throw of the plunger 26 or the thickness of the work piece is such that when engagement of the work piece and the marking edges 8| occurs the plunger is at the end of its downward stroke and the work piece is perforated, the plunger will immediately rise and the springs H, in elevating the stripper plate to strip the work from the tubes 60, also serves to release the pressure of the stripper plate upon the pins 96 and 91, whereupon the marker plate 19 falls to its normal, retracted position. However, if the throw of the plunger 26 or the thickness of the work piece is such that when engagement of the work piece with the marking edges 8| occurs the plunger has not yet reached the end of its downward stroke, it is obvious that the plunger, acting through the stripper plate 68 and the work,

piece, subjects to downward pressure not only the lever pins 96 and 91 but also the marking edges 8|, and hence the marker plate 19 itself. As some part of the die structure would undoubtedly break or give wayunder these conditions if the connection between the marker plate 19- and the levers 89 were solid, accommodation to prevent breakage is provided by the gap between each button 88 and its. associated post 85 and by the normal mounting of the marker plate 19 upon the springs 87.. By reason of this construction the downward pressure exerted by the plunger 28 on the marker plate 19 while the pins 96 and 91 are also being pressed downwardly serves merely to compress the springs 81,

which compression makes descent of the marker plate under the pressure of the plunger possible.

The marker plate is thus mounted yieldingly not only for movement upward and away from the support afforded by the die base 43 but also for movement toward it.

Upon elevation of the plunger 26, the stripper plate 68 is released upward, and this is accompanied by the stripping of the work piece from the tubes 60 and the resumption by the marker plate 19 of its normal, retracted position. The.

cycle of actuation which began with the depositing of marking substance upon the marking edges 8| is then completed by pulling the die structure far enough forward in the ways 50 and 5| so that the work piece may be removed from the stripper plate 68, this last operation being most conveniently done by reaching over the roll 9, which will now be advanced ahead of the die structure by reason of the engagement of the die base 43 v.

with the fingers I44 and I45, and lifting and pullmg the work piece rearwardly to release it from the clips 18. This cycle being completed, the next cycle is begun by continuing to pull the die structhe work piece begins to descend. Instead, the

work piece will be pressed downward into engagement with the edges 8| of the plate 19, which will then descend in engagement with the work and will'thereafter rise during further descent of the plunger and its withdrawal, respectively.

While the planes of the tops of the tubes and the marking edges 8| have been herein illustrated generally as being normally in the planes of the top and bottom surfaces of the stripper plate 68, respectively, variations from these showings are of course within the scope of the present invention. The throw of the levers 89 may also be varied in connection with the foregoing. Infact, nothing herein explained is to be interpreted as limiting the present invention in the scope of its application to use in connection with the particularstructure or the parand it is to be understood that the particulars herein illustrated are not essential, since they may be variously modified within the skill of the artisan without in any way departing from the true scope of the actual invention, characterizing features of which are set forth in the following claims which contain generic terms and expres slons that are inclusive of various modifications.
